Description
Potassium chloride solution ROTI®Star 0,1 mol/l - 0,1 N is a volumetric solution of potassium chloride with empirical formula KCl, CAS number 7447-40-7 and EG number 231-211-8. The compound has a molar mass of 74,56 g/mol. Offered as a ready 0,1 mol/l (0,1 N) aqueous volumetric solution in a 500 ml plastic bottle, it is intended for analytical laboratory work that requires a defined potassium chloride concentration. The density is 1,003 g/cm³ and the boiling point is 100 °C, in line with a dilute aqueous chloride solution. This ROTI®Star volumetric standard solution from manufacturer Carl ROTH belongs to the range of volumetric standard solutions used in wet-chemical analysis and titration. Potassium chloride (KCl) serves in analytical chemistry as a well-defined chloride salt; this 0,1 mol/l - 0,1 N volumetric solution is prepared for titration and related volumetric methods. The 500 ml plastic pack supports everyday use on the analytical bench. It is listed among analytical chemicals for volumetric standard applications and is supplied ready for use at 0,1 N.

Questions about Potassium chloride solution ROTI®Star 0,1 mol/l - 0,1 N, 500 ml
What is this article?
Potassium chloride solution ROTI®Star 0,1 mol/l - 0,1 N, 500 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Lab chemicals.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
